Specification of Letters Patent.

Patented Jan. 14. 1913.

Application filed November 22, 1905 Serial No. 529,358.

T 0 all whom it may concern:

Be it known that I, FRANK H. LEIIMAN, a citizen of the United States, residing in the city of Lebanon, county of Lebanon, 5 and State of Pennsylvania, have invented certain new and useful Improvements in Sash-lVeights, of which the following is a specification.

My invention relates to improvements in sash-weights and particularly to what are known as sectional sash-weights, in which aseries of similarly formed units or sections, having corresponding engaging and locking means, are provided for connection one with another, whereby any number of sections necessary for counter-balancing a.

windowsash of any weight may be readily assembled and suspended in the. sash box.

One of the objects of my-invention is to provide in a sectional sash-weight special and novel means for attaching a cord, chain, or other suitable suspending medium, to the weight, said means consisting of opposed laterally extending arms having notches 5 therein or keepers formed thereon, whereby a U shaped hanger having opposed terminal loops is adapted to be detachably enaged by said arms and to be securely inter- -ockd therewith when the hanger is brought into longitudinal alinement with the weight. Another object of my invention 18 to sup ply a weight of this type, which can be easily and cheaply manufactured without the use of a core in molding, and which will be very strong and durable and capable of withstanding the rough usage incident to tumbling, handling and shipping. With the above and other objects in view, the invention consists in the novel construc- 0 tion and arrangement of parts hereinafter fully described, illustrated and claimed.

In the accompanying drawings, Figure 1 is a side elevational view showing two weight sections coupled together, and a third section, partly in section, in the entreme angular position necessary for efiecting ts engagement with the second SGGtlOIL- Fig. 2 IS a rear elevational view of asection. Fig. 3 is a perspective view of the same.

65 l iorizontal supported. position to a vertical Fig. 4 is a perspective view of the novel suspended position. by means of a chain or rope.

Like characters of reference indicate like parts throughout the several views.

Referring now to the drawings, 1 designates a section of a sash-weight embodying my invention, comprising an intermediate body portion which is preferably rectangular in cross-section and is provided at its upper and lower ends respectively with terminal male and female engaging and locking members, the former consisting of a substantially centrally disposed and laterallyrestricted continuation of the body portion producing the tongue 3, and the latter of the two oppositely disposed and spaced extensions of the lateral portions of the body forming the hooks 9, the space 1 1- between orally projecting arms 4 of the correspond.

ing adjacent section; While a recess 15, formed in the lower rear part of the weight body contiguous to and of equal width with the space 14 between the hooks 9, and terminating at its forward end in an abutment 12 lying in the same plane substantially with the front face of the shoulder 8, is adapted to receive the shoulder of such corresponding adjacent section, and, by the cooperation of saidabutment and shoulder, the former acting as a stop to prevent forward movement of the latter, to prevent accidental disconnection of the sections when the same are hung in vertical alinenientin the manner hereinafter explained. It will be observed that in the present instance the recess 15 does not extend from one side of the weight body to the other, but that the same terminates forwardly at the abutment 12, the plane" of said abutment and the front ter it 'ishighly desirable that ent invention provided tional sash-weights to the In sectional sash-weights of this characthe engaging and locking members should be so constructed as to permit of the several sections constituting a given weight being very closely and compactly nested together, in order that the least possible unoccupied or dead space may be left between the sections, and so that the mass of the united sections may approximate as closely as possible that of a solid length and similarcross section, further purpose 'of providing convenient means for readily and positively connecting the weights to a chain by means of a hanger which may be easily and quickly adjusted and so interlocked therewith as to obviate accidental disconnection,

and for the I have in my presnovel and very efiicient means, the same consisting of a specially devised U-shaped hanger shown in Fig. 4, adapted to co-act with notches 6 and lugs 5 formed on the laterally extending arms 4 of the tongue 3.

While I believe this mode of securing secsuspending cord or chain, by the use of a hanger and specially formed laterally extending arms provided on one end of the weight section, to be entirely new and heretofore unknown in the art, and do not therefore wish to limit myself to any particular details of construc .tion, I preferably employ a hanger U shaped,

as stated, and bent up having two loop-bearing arms I) united by a return-bend a whereby said arms are nor mally and yieldably held in parallel relafrom spring wire,

- tionship with each other. The loops 0 carried by the arms 6 are preferably arc-shaped at their lower portions and have their upper portions formed i by convergingly continuing the opposite sides of the arc-shaped portions upwardly to the arms. The laterally extending arms 4 of the tongue 3 of the weight section have their extremities shaped cross-sectionally similarly to the loops 0,

being elongated preferably toward the front of the section and having converging upper and lower front faces and rounded or cylindrical rear faces,

whereby when the hanger is presented to the shown in Fig. 1 by the dotted lines.

- j the loops have been thus section at an angle slightly greater than a right angle and the arms 6 thereof sprung slightly apart, the loops may be slipped over said elongated extremities of the arms, as

6 formed in the arms 4 adjacent the opposite sides of the tongue permit the hanger, when slipped over the extremities and allowed'to return to their normal parallel relationship, to be turned into line with the longitudinal axis of the section, as shown by the full lines in Fig. 1, in which [position of the hanger the front portions '5 of said extremities of the arms 4 non-sectional weight of equal tangentially and,

I of the weight;

ily secured to the return-bend of the hanger, 10

as shown in Fig. 5.

In operation, two of my improved weight sections may be coupled together by pre senting the tongue member of the second section to the double-hook member of the first at an angle of approximately forty-five degrees, in which position .the tongue may be introduced into the space 14 between the hooks and the shoulder 8 passed behind the abutment 12 and caused to ent'er the recess 15, while the laterally projecting arms 4 enter the hook openings 10. When now the second section is permitted to swing into alinement with the first, the sections will be securely locked together against accidental disengagement by the abutment 12 actin on the shoulder 8 and preventing forwar movement of the second section so long as the sections remain thus alined. In attaching the first of a series of sections to the chain orrope, the loops of the hanger are first slipped over the laterally extending arms 4, and the hanger is then turned into line with the section, when it will be securely locked thereto by the operation of the grooves 6 and the keepers 5 as before described; and the rope or chain 13 is then attached to the hanger.

Having thus described my invention, what I claim as new and desire to secureby Letters Patent, is

1. A sash-weight having at one end laterally and oppositely projecting arms, and cone-shaped lugs formed on the outer ends of sa'id arms, said lugs having their greater axes at right'angles to the axes of the arms and at rightangles to the longitudinal axis 2. The combination with a sash-weight having laterally projecting alined arms at one end thereof with pear-shaped lugs formed on the outer U shaped hanger having a resilient return bend and provided with rigid closed-loop, pear-shaped terminal members, whereby said weight is adapted to be detachably connected and interlocked therewith.

3. The combination with having and lugs of a given conformation formed on the outer ends of'said arms; of a U shaped hanger having a resilient return bend with rigid closed-loop terminal members, said terminal members being with said lugs.
